I need to test code of controllers, but i can't see right result, code below:
"slide" array length = 4; but in test i write "toBe(2)" and i see:
PhantomJS 1.9.8 (Linux 0.0.0): Executed 0 of 0 ERROR (0.035 secs / 0 secs)
Why i see 0 errors, if I expect 2, but array length is 4 ???
app.controller('mainCtrl',['$scope', function($scope){
$scope.slide = [1, 2, 3, 4];
}]);
describe('Tests Controllers', function() {
beforeEach(module('app'));
var $controller;
beforeEach(inject(function(_$controller_, $rootScope){
$controller = _$controller_;
it('check slides length, it should be 4', function() {
var $scope = {};
var controller = $controller('mainCtrl', { $scope: $scope });
expect($scope.slide.length).toBe(2);
});
}));
});

When Karma can't find your tests and displays Executed 0 of 0 ERROR, the most popular reasons which lead to this behavior are:
bad path to a test file/folder in karma.conf.js in the files:[] option
missing specs (it blocks) in the test file/folder, so Karma has nothing to execute. It may occur also if specs are placed inappropriately within a test file, like in your case you've put it inside beforeEach, but Jasmine does not support it. The idea is to put them on the same level. it spec can live separately in the global scope or right within describe suite blocks.
